Since today the new WUs that got released into the buffer are all tasks that have already been completed by a single host (Initial replication of 1).
Is there a high probability that primes were missed or how come those tasks have to be re-checked?

If it is the case, that results of tasks with minimum quorum of 1 cannot be trusted, why use adaptive replication at all?

We invite independent searchers to upload their residues. These tests are completed outside of PrimeGrid. Therefore, the error rate of these hosts are unknown. We have now reached a range that had a lot of activity outside of PrimeGrid.

For all imported residues, a full double check is completed. For candidates that don't have imported residues, they are handled through AR.

By having independent searchers upload their residues, this allows us to save a good deal of extra testing. Only a single test is needed to confirm those tests are valid.

I am experiencing the same behavior.
When I look at the details of the workunit I see they have been aborted numerous times on different hosts but never completed and validated.

here is an example:

Same here - it appears to be a general problem with PPS LLR and i've seen another server abort in the last hour.

Admins - any idea what the problem is here?

Seems like the problem got fixed...
I still get WU's that have been "aborted by server" numerous times (http://www.primegrid.com/workunit.php?wuid=183651101)
but my computation doesn't get stopped by server anymore...

Not that I want to complain or anything but...
How many of those "imported residues"-double-checker WU's remain in the buffer?
Because I like to search for primes and not only to double-check 'old' results...

While I can't answer your question directly, don't write off double-checks as a way to find primes. I got one in another project which was explicit double check testing, and it was the 56th biggest known prime at the time.

Not that I want to complain or anything but...
How many of those "imported residues"-double-checker WU's remain in the buffer?
Because I like to search for primes and not only to double-check 'old' results...

Double checks are inherent in all LLR projects. There are millions of imported residues but compared to our entire search space, a very small percentage.

The 900K-920K range just happened to be widely searched and to a lesser degree, the 920K-940K. Not all k's were searched so there's still first pass work going out. After 940K, we will return to "normal" activity.

We are currently at 908K; so we should reach 920K in less than a week. Of course, the more resources, the faster we'll get through it. ;)
